Hedy's film career was mostly in the 30s - 50s. Some of her most well-known films are Algiers, Comrade X, and Samson and Delilah.

She was typecast into roles where she said very little and was generally present for her looks. As a result, it is said that she took up inventing to relieve boredom.

•

She invented an improved traffic stoplight and is credited with coming up with the patented technology that led to Bluetooth, wifi, and other modern communication technologies.

Her first husband was an Austrian arms merchant, and during WWII the ease of jamming radio-controlled torpedoes and changing their track caught her attention. The technology she patented allowed a later version to be built into Navy ships (1960s) which allowed for increased security of military operations.

•

She had no formal training in these technologies and was named (along with her co-inventor) to the National Inventors Hall of Fame (2014).

1953 - Became a US citizen.
